Earth Electrode Concern.

Zoomup
I was working in a large back garden today. The garden shed was connected to an old caravan supply (caravan gone) and the underground S.W.A. cable from the house had been  converted to TT earthing originally for the caravan and now for the shed sockets and lighting. As an earth electrode somebody had used a length of  10mm galvanised threaded rod (studding). What are your views about its suitability please?

    are you sure about 10mm^2 - that is is pretty thin - a 5mm stud rod is going to meet that. (Pi R squared etc.) 10mm dia would have seemed more reliable.


     




    Oops. You are correct Mike. It is actually 16mm diameter when installed vertically. Sorry about that.
